Addendum: Scalers Group Additional Features of the Scaler Products Group according to the Master-Firmware Ver-2.33 Release. 1. This version requires Slave Firmware version 1.06 or higher. The version can be seen in the INFO section of the on-screen menu. Contact your Kramer service center if you have any questions. 2. Improved functionality lets you select the PIP source via the RS-232 command. Sending an inappropriate PIP source command (request video PIP source while the main video input is selected; or the same for graphic sources) will not cause the unit to operate erroneously. In such a case, the unit will ignore the command and return the message: ineffective source. This option does not apply to the VP-719DS. 3. Added PIP position(s) commands in the RS-232 protocol. These commands let you input the absolute value (from 0 to 36) of the horizontal and vertical positions of the PIP. For details, see the protocol table. This option does not apply to the VP-719DS. 4. Added new output resolution 1280x768. This resolution is marked with an asterisk * to attract your attention to the fact that this is not a standard VESA resolution and its parameters vary from manufacturer to manufacturer. Therefore, this resolution must be used with caution. It is also possible to use the parameters of this resolution in combination with the User Defined resolution (see below). There is also an RS-232 command for this resolution. For details, see the protocol table. 5. Added 50 Hz output refresh rate. This is for special cases only. Many of the modern screens and projectors have difficulties working with such a low frequency. 6. In the OSD under UTILITIES>ADVANCED there is new item: Input Button. This item defines an action after repeatedly pressing the same input selection button. This item has following options: FREEZE/BLANK this is the current situation (quoting from the user manual: Press again (when the LED illuminates) to freeze the image; the LED flashes. Press once again (when the LED flashes), to display a blank screen; the LED flashes more slowly)). This remains the factory default FREEZE pressing the button toggles between LIVE and FREEZE BLANK pressing the button toggles between LIVE and BLANK IGNORE after selecting the source, the button is ignored The settings also apply to the input buttons on the IR control. 7. Under the Utility>PIP Setting there is new item: PIP Frame. This feature allows the enable/disable yellow frame around the PIP through the OSD or the new RS-232 command: L 50AF. The RS-232 command allows PIP frame enable/disable while the PIP is activated. However, before doing it via the OSD you must switch the PIP OFF. While the frame is activated, pressing the UP and DOWN buttons on the front panel and on the IR remote control would toggle through the PIP size settings. This option does not apply to the VP-719DS. P/N: 2900-0070144 A1

Addendum: Scalers Group 8. Under the Utility>Output Setting>User Mode Setting there is a new option: Set Current. This feature lets you apply the parameters of the currently selected output resolution to the User Define output resolution (Utility>Output Setting>Resolution). This set of parameters can be used as a starting point to adjust parameters according to the requirements of the signal receiver. The changes to the User Define parameters are applied immediately and require confirmation in the same part of the OSD. 9. In the OSD under UTILITIES>ADVANCED there is new item User Define Measure. This feature lets you modify the automatically detected parameters of the input graphic signal and save them in one of 3 sets for further use. The changes are applied in real time and therefore can be monitored directly on the screen. This feature is especially useful in working with non-standard input resolutions. The following parameters can be changed: H Total: H Start: H Active: V Start: V Active: Ch Pump: Color: Horizontal total Horizontal active start point Horizontal active region Vertical active start point Vertical active region Charge Pump current Color Format 10. Under the Utility>PIP Setting>PIP Size, there is a new option: User Define. This feature lets you set the size of the PIP to your exact needs. To use this option, select User Define, then press the PIP User Define bar and set the PIP V-size (0-255 1 ) and H-size (0-255 1 ). This option does not apply to the VP-719DS. 11. By pressing the +, -, UP and DOWN buttons continuously, you can speed up their response. For example, to roughly set the brightness to a higher level, open Brightness and Contrast >Brightness, and press and hold the + button. For step-by-step response, press and release these buttons as many times as needed. 12. New firmware supports an updated set of RS-232 protocol commands. These commands are available on our Web site at http://www.kramerelectronics.com 13. Under Geometry>Scale>Aspect Ratio there is a new option: User Define. This feature lets you adjust the geometry of the outputted picture. 14. A new refresh rate for HDTV resolutions. This new feature supports the HDTV outputs with 50Hz refresh rate 2. 1 255 corresponds to a full screen 2 This option applies to machines that support HDTV resolutions A2

Understanding the Seamless Switcher / Scaler 6.2 Understanding the PIP Button Feature The Picture-in-Picture inserter (PIP) is used for the simultaneous display of video and graphic sources, and lets you display: An inserted video source 1 PIP over a graphic source 2 display An inserted graphic source 2 PIP over a video source 1 display Your Seamless Switcher / Scaler automatically recognizes and displays only the relevant sources, as the following 2 examples illustrate: Choosing the AV 1 PIP source when the VGA input is selected, will insert the composite video source over the VGA graphic displayed on the screen. You can choose a component, YC 1, YC 2 or AV 2 PIP source 3 (instead of the AV 1). You cannot choose VGA 1, VGA 2 or DVI 4 Choosing the VGA 1 PIP source when the AV 1 input is selected, will insert the VGA graphic source over the composite video displayed on the screen. You can choose a DVI PIP source 3 (instead of the VGA 1). You cannot choose AV 2, YC 1, YC 2 or component 5 6.2.1 Activating the PIP Feature To activate the PIP (which illuminates the PIP LED), do one of the following: Press the PIP button 6 Switch on the PIP functionality via the OSD Menu (see Figure 35) Press the PIP key on the infra-red remote control transmitter (see Figure 49) When the Source Prompt is ON (see Figure 41), the PIP is enclosed by an orange frame, and the OSD PIP status appears superimposed over the top right corner of the screen for a few seconds, as Figure 5 illustrates. After a few seconds 7, the orange frame and the OSD PIP status automatically disappear 8. Activating the PIP subsequently cycles between the PIP with the orange frame and no PIP. 1 That is, composite, s-video or component 2 That is, DVI or VGA 3 As long as it is connected and switched on. Otherwise, choosing it will display a blank screen 4 As these are graphics sources and you cannot insert a graphics PIP over a graphics source 5 As these are video sources and you cannot insert a video PIP over a video source 6 Item 24 in Figure 1 7 By default, 20 seconds. But you can reset the timeout (from 3 to 60 seconds), see section 7.3.6.6 8 Trying to activate the PIP again while the PIP is still enclosed by an orange frame deactivates the PIP 13
